    Sammanfattning : The duodenal epithelium secretes bicarbonate ions and this is regarded as the primary defence mechanism against the acid discharged from the stomach. For an efficient protection, the duodenum must also function as a sensory organ identifying luminal factors. LÄS MER

  4. 3. The Duodenal Mucosal Bicarbonate Secretion : Role of Melatonin in Neurohumoral Control and Cellular Signaling

    Författare :Markus Sjöblom; Gunnar Flemström; Olof Nylander; Karl EO Åkerman; Per M. Hellström; Uppsala universitet; []

    Sammanfattning : The duodenal lumen is exposed to aggressive factors with a high potential to cause damage to the mucosa. Bicarbonate secretion by the duodenal mucosa is accepted as the primary important defense mechanism against the hydrochloric acid intermittently expelled from the stomach. LÄS MER
